The invention relates to disintegrator gas washers and has reference more particularly to an improvement in the agitating means, that is, the disintegrator bars employed in the above type of apparatus.

An object of the invention is to provide an apparatus as above described, with novel means for increasing the effective washing surface of the same, which thus results in an increase in the frictional resistance to the passage of gases, causing a greater cleaning of the gases and more efficient operation of the machine.

Another object is to provide a disintegrator with rotary and stationary bars formed in a particular shape to increase the area subjected to contact by the gases so that the dust particles in the gas and the washing medium will be thoroughly mixed and the wetted surface for collecting the dust particles will also be increased.

Another object is to provide a standard type of disintegrator gas washer with novel shaped stationary and rotary bars for agitating the gases, which will materially increase the surface contacting the gases to secure a greater scrubbing effect without requiring additional power for its operation.

Another object of the invention is to provide an improved disintegrator gas washer which will require less power and less washing medium for producing the same cleaning effect as heretofore secured and which will be simple in construction, fulfilling all requirements of service and manufacture.

A still further object is to provide improvements in disintegrator bars, which can be readily applied to the standard type of disintegrator gas washer without necessitating any change or alteration in structure and wherein the rotary bars will have a shape or contour to reduce the power input thereto, while the stationary bars will be so shaped as to increase the agitation and scrubbing effect.

With these and various other objects in view, the invention may consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specification, drawings and claims appended hereto.

In the drawings, which illustrate an embodiment of the device and wherein like reference characters are used to designate like parts Figure l is an eievational View, parts being shown in section of a standard type of disintegrator gas washer with which the present invention is concerned;

Figure 2 is a fragmentary sectional view looking toward the axis of rotation of the rotating elements; the righthand side being taken on a circumferential line just outside of a set of stationary bars, showing one set of rotating bars beyond said stationary bars; and the lefthand side of the figure being taken on a circumferential line just outside of one set of rotating bars, showing stationary bars beyond them, and showing a second set of rotating bars beyond the stationary bars.

Figure 3 is a fragmentary sectional View showing the alternate rows of stationary and rotary bars;

Figure 4 is a sectional View showing a modified form of stationary bars; and

Figure 5 is a sectional View showing still an.- other modified form of both stationary and rotary bars.

The standard type of disintegrator gas washer, with which the present invention is concerned, is disclosed in Figure 1 and includes a housing 10 supported upon a suitable foundation of concrete or similar material 12 and constructed to provide a plurality of gas inlets 13 which conduct the gas to an interior chamber 14. Suitably journaled upon supports 15 provided on both sides of the housing 10 is an operating shaft 16 to which is centrally secured a circular plate 17 of fairly large diameter. The washing medium, preferably water, is conducted to the housing 10 by means of supply pipes 18 and is discharged from the interior pipe 20, located adjacent the shaft 16 and within the spraycones 21; The spray cones comprise cylindrical members' having a slightly tapered formation and which are suitably secured to the plate 17 concentric with the operating shaft 16. The washing medium thus discharged within the spray cones 21 is discharged in finely divided form to the chamber 14 by means of the perforations 22 provided in the cones for the purpose.

The active elements which function to thoroughly mix the washing medium and the gases, both of which, as is seen, are discharged into the chamber 14, comprise a plurality of rotating disintegrator bars 23, suitably secured at their inner end to the plate 17 and a plurality of stationary bars 24, suitably secured at their outer end to plate 25. Both the rotary and stationary bars are secured and arranged in rows concentric to the operating shaft 16 and are disposed so that the gases in traveling outwardly to the outlet 26 pass alternate sets of stationary and rotary bars.

The scrubbing effect is obtained by intimately associating the particles of dust contained in the gas with the washing medium, and the present invention is primarily concerned with the-shape or surface contour of the disintegrator bars. As shown in Figure 3 the stationary bars may comprise v-shaped members 30, while the rotarybars 31 are formed rectangular in cross-section. A slightly modified construction is shown in Figure 4, wherein the stationary bars 40 are curved to present a broad curved surface for contact by the gases. The rotary bars 31 are, as shown in Figure 3, of rectangular shape in cross-section. The stationary bars and 40 are provided with a surface contour such that the maximum surface area is presented for contact with the gases and it has also been found practical to so position the bars with reference to the rotary bars, that their broad side will be opposed to the flow of the gas and washing medium. Stationary bars 30 and 40 of angle and curved cross-section thus present a maximum wetted surface which will collect the dust particles by actual contact and which will also function to cause a maximum agitation of the gases to secure intimate association of the gases and washing medium. The rotating bars 31 have been designed with plain flat surfaces so that they present a minimum frictional resistance, whereby the power input to the same is substantially reduced. As the bars 30 and 40 are stationary, these have been designed so that they function to cause a maximum turbulence of the gases, which are hurled with great force upon and over the broad surface of the same and since they are positioned to oppose the gas and water flow, a greater degree of cleanliness is obtained without an increase in power requirements;

In Figure 5 the construction is modified so that the stationary bars 50 are formed with plain fiat surfaces being rectangular in cross-section, while the rotating bars 31 are likewise of rectangular cross-section. Practice has revealed that such an arrangement of flat bars gives good results especially when they are installed insuch a manner that the inward end of the rotating bars of one row are in advanced position with reference to the direction of rotation while the bars of the next adjacent rotating'row are in reversed direction, having their outer end leading with respect to the direction of rotation, presenting a diagonal arrangement of rotating bars with the stationary bars-separating the rows and being parallel to the axis of the disintegrator, as shown in Figure 2, in which position the gas and water mixture enter with the least amount of impact losses and the powerof requirement is therefore reduced to a minimum. This construction in operation causes a zig-zag motion of the gas and water mixture through the disintegrator, with the result that an intensive cleaning effect is obtained. This arrangement of the rotating bars may be also applied withincreased efficiency when the stationary bars are of V formation as shown in Figure 3, or of curvedformation as illustrated in Figure 4.

t" is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration andnotlimitation, as various and other forms of. the device-will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
